New Extensions app is missing metadata in gnome-software
Since the option "Show Details" for the new Extensions app is available after right click on the app icon, we should generate the appstream data for gnome-software for the app.
gnome-software-3.35.91-2.fc32.x86_64 appstream-data-32-5.fc32.noarch
Reproducer:
1.Open gnome-shell overview
2.Right click on the Extension app
3.Choose Show Details
Result:
Error message in gnome-software: Sorry! There are no details for that application.
